Effects of bone marrow mesenchymal stem cell combined with platelet-rich plasma treatment of bone nonunion after long bone fracture surgery on bone metabolism and cytokines
Objective: To study the effects of bone marrow mesenchymal stem cell combined with platelet-rich plasma treatment of bone nonunion after long bone fracture surgery on bone metabolism and cytokines. Methods: Patients who were treated in our hospital due to bone nonunion after long bone fracture surgery between March 2011 and October 2017 were selected and randomly divided into two groups, combined group received bone marrow mesenchymal stem cell combined with platelet-rich plasma therapy, and control group received bone marrow mesenchymal stem cell therapy. The levels of bone metabolism markers and growth cytokines in serum as well as the expression of bone metabolism-related signal molecules in peripheral blood were determined before treatment and 1 month after treatment. Results: Compared with those of same group before treatment, serum PINP, OPG, BALP, VEGF, TGF-β1, IGF-I, IGF-II and bFGF levels as well as peripheral blood Runx2, Wnt1, Wnt3a and β-catenin expression intensity of both groups of patients significantly increased whereas serum β-CTX and RANKL levels as well as peripheral blood NOX4 and NF-κB expression intensity significantly decreased after treatment, and serum PINP, OPG, BALP, VEGF, TGF-β1, IGF-I, IGF-II and bFGF levels as well as peripheral blood Runx2, Wnt1, Wnt3a and β-catenin expression intensity of combined group after treatment were higher than those of control group whereas serum β-CTX and RANKL levels as well as peripheral blood NOX4 and NF-κB expression intensity were lower than those of control group. Conclusion: Bone marrow mesenchymal stem cell combined with platelet-rich plasma treatment of bone nonunion after long bone fracture surgery can be more effective than bone marrow mesenchymal stem cell monotherapy to improve the bone metabolism and increase the cytokines.
